Pascha is factoring the polynomial, which has four terms.3x3 – 15x2 + 8x – 403x2(x – 5) + 8(x – 5)Which is the completely factored form of her polynomial?

Group the first two terms and the last two terms: 3x³ − 15x² + 8x − 40 = 3x²(x − 5) + 8(x − 5). Both groups contain the common factor (x − 5), so factoring it out gives (3x² + 8)(x − 5). This is choice C.
